Application filed February is, 1924. Serial No. 693,243.

The object of this invention is to provide a hinge for windows, transomsand the like,

. which may serve both as a hinge and a support for the window ortransom when open. The invention is fully disclosed in the descriptionand claim following, reference, being had to the accompanying drawing,in -which I Fig; l is a view in perspectiveillustrating a cellar windowwith the improved hinges attached. Fig. 2 is a sideview of the hinge,

with a fragment of sash attached. Fig, 3:

- is a front View of the same, but showing some modification instructure.

In the drawing, the numeral 5 denotes'a cellar window sash, such windowsbeing usually hinged at the. top so as to swing inwardly and upwardly.The connnonlrneans of support for the sash when so ralsed 1s a hook andeye holding the window in the single wide open position. In deepcellarsthis fastening is so high as to require a step for the operator, and theuse of both hands in hooking up the window. 'Hooksor'buttons arealsorequired for fastening the window in closed' position. The hinges ;now'

to be described are adapted to lock the window in closed position, aswell as to support it atany desired open position. a

In the drawing, the numeral 6"desig'na'tes the hinge member whichissecured to the window frame 7 This comprises a 'wallplate 8 suitablyprovided 'with'holes 9 for fastening screws '10, and a quadrant-shapedwing 11 disposed at right angles to the wallplate, The other, member hasa similar wall-plate 12, with screw-holeslB, and a lesser wing 14 alsoat right angles to' the base. Near the upper end this wing is pierced,as is the other member near its upper and inner 'angle, for a pivot 15,whi'ch is preferably a small bolt that may be easily removed whenit isdesired to take out the window sash. The lower end of'the wing 14: isformed as a stirrup 16 to engage the curved edge of the quadrant," asshown. Holes at 17, whichare in register lwhen the window is closed,serve for the locking of the window by pins or nails18.

In the detail figures of the have shown a plurality of means for holdingthe window open by friction, In Fig. 2

claim 4 V In ahmge, a fixed member consisting of a drawing I this iseffected by the :wedging actionof the quadrant edge in the loop of thestirrup. V

The dotted line in this figure indicates an arc of which the pivot isthe center, showing thatthe pivot is setalittle off-center with respectto the curve of the wing. It is evident" that the raising of the sashwill serve to wedge the parts of the hinge together, and the friction ofthe parts so wedged is sufficient to support the sash. As shown in. Fig.2 this support would. be m'ainly effective when the sash is completelyelevated. In Fig. 3, however, the friction applies to the hole curve ofthe'quadrant, and the sash is supported at any point of elevation. Inthiscase the stirrup, which should be slightly elastic, is made to pinchthe quadrant with F enough frictional ,effectto support'the sash.

" For this purpose the. stirrup may be pro.- v'

vided with a tension bolt 19. A corrugated edge 20 for the quadrantenhances the grip of the stirrup, but is not indispensable. as.

sufiicient tension may be obtained on a plane surfaced wing, as shown inthe Othe fi u Of the drawing. v i

The hinge members are preferably formed of thick sheet steel, and foruse in cellars or other damp places should besuitably protected fromrust, as by galvanizing.

Having thus described my invention, I

plate adapted to be fixed to a window frame and a quadrant shaped wingoutstanding from the plate at right angles thereto,'a

movable member consisting of .a plate adapted to be fixed to a sashpivoted. in the frame and an outstanding quadrant shapedi wing disposedat right angles to the plate thereof, the second wing being pivoted atits axis to the axis of thefirst wing to be off center thereof, aU-shaped stirrup fixed to the edge of the second wing and straddling theedge of the first wing so that its free end frictionally' engagestherewith, a bolt extending through'the sides of the stirrup to adjustthe frictional engagement of the free end of the stirrup with the edgeof the first wing.

In testimony whereof I aflix my signature.
